So I was looking at this thread the other day and thought that straightening with a peening hamer seemed like a great idea.

I make kitchen knives out of aeb-l and hate dealing with warps. I don't like using heat as I don't want to mess up my temper and have snapped a few blades prying too hard. After seeing the above thread I was going to make a peening hammer from a tungsten tig welder electrode but someone suggested that a bead blaster will straighten a blade. I ordered some extra course media from Amazon that arrived today.

Within 1 hour I had straightened 5 blades. These are aeb-l at 62 hrc at .110 thick. The first one I tried I was disappointed when the curve was still there. Then I realized that it had over curved. It only takes a couple minutes to get it very close. A quick pass on the flat platen finishes it off. It worked great for gradual bends. Sharper bends at the end of a tang still required heat and bending. A 2.5" Nikiri took a bit more time as well. I don't know how well this work on thicker stock but it's great for .110.
